They sound decent. Yes, they provide all those extras with it but honestly I'd rather have a pair of earphones WITHOUT all the extras as long as they last a few months.
The right earphone stopped working after about 2 months. Honestly, I had read the reviews here before buying and there were people who had the same issue (some after just 1 month) but i bought them anyway. Lesson learnt, I guess.

There are lot of reasons why earphones can fail. With the +9k units Massdrop has sold I can verify that the defect rate is very low. However I also understand that even one case is too much, thus, we also provide 1 year warranty and we are happy to help. Could you please contact either Massdrop or us so that we can start the replacement process? Our contact details are here:
